[vtkusers] Some VTK 5 information - KD Tree searchs

[Tuhin Sinha]

Hello users and Ken,

  Is there any thought at Kitware about refining the geometric search
capabilities in VTK?  One of the warnings in the vtkPointLocator class
documentation is that KD-Trees are better suited to handle geometric
searching... yet VTK has always been sans KD-Trees.
  Our group uses Dr. David Mount's ANN package and wraps it into VTK for
KD-tree searchs.  The wrapped code greatly enhances the performance of
some useful VTK classes, e.g. vtkIterativeClosestPointTransform.  There
may be some licensing issues with that package that make it unsuitable
for VTK, however I have seen other OpenSource packages (i.e. CGAL, and
surprisingly ITK) that also have KD-Trees in them.  Maybe some code from
those packages could be incorporated into VTK.  Is there any desire at
Kitware or from the users to see this functionality in VTK?

Best regards,

Tuhin Sinha
